Petition for Exemption
Docket No.: FAA-2018-0880.
Petitioner: Rolls-Royce plc.
Section(s) of 14 CFR Affected: § 33.14 at amendment 33-10 and § 33.83(d) at amendment 33-17.
Description of Relief Sought: Rolls-Royce requests a time-limited exemption from 14 CFR 33.14 at amendment 33-10 and § 33.83(d) at amendment 33-17 for the Rolls-Royce Trent 1000-AE3, 1000-CE3, 1000-D3, 1000-G3, 1000-H3, 1000-J3, 1000-K3, 1000-L3, 1000-M3, 1000-N3, 1000-P3, 1000-Q3, 1000-R3, Trent 7000-72, and Trent 7000-72C engine models. Rolls-Royce seeks to temporarily exclude the intermediate pressure compression system from consideration of vibration stresses combined with steady stresses, which exceed the endurance limits of the material concerned. Rolls-Royce states that compensating factors will meet the protections afforded by 14 CFR 33.14 at amendment 33-10 and § 33.83(d) at amendment 33-17.
